Sorry but I have NEVER had any problem with Behringer gear and I have used (and still am) a very large amount of their stuff.
Sure, there might be the odd piece of equipment that is a 'lemon" but isn't that the same for virtually every piece of equipment manufactured today (howmany thousands of vehicles have Toyota recalled over the past few years, didn't Ford have to recall hundreds of vehicles for a major tyre problem , but how many people do we hear rubbishing either of these two companies?????).
I believe that a lot of the complaints about Behringer products come from people who have NEVER owned a piece if their equipment but like to talk knowingly because of some deluded idea that if it is not worth mega dollars then it obviously is no good --- I think it is generally known as "the BS factor".
My first Behringer product was a microphone I purchased while working at the Sydney Opera House (you can't get much more professional than that !!!!!). When I heard the result I was amazed as
the other microphones we were using were worth in the thousands. I did a recording with the Behringer mic and one of our normal mega dollar mics (on a world famous symphony orchestra) and could not hear the difference. I then played the recording to a number of "professional" sound recording engineers from both within and outside of the Opera House --- most of whom had previously rubbished all Behringer products --- and none of them could tell the difference, but ALL were amazed when I told them the brands of the two mics I had used.
Since then, I have purchased three Behringer consoles for professional live theatre applications (MX800, MX9000, MX3282) and all have performed excellently for more than ten years (just about to update one of these to the new Begringer X32 digital console --- 20K+ sold even before it was released), numerous items of their outboard equipment.
My own studio uses their Truth monitors (I have no idea why they stopped producing their Thuth Sub as it was possibly the best on the market for studio use), numerous active DI boxes (as have all the theatres) and I have never had a failure and I have just finished designing and building a recording studio for a local community music association and apart from the recorders (Alesis HD24 and Alesis Masterlink) the entire studio (mics included) is Behringer and the studio is producing the most supurb sounding recordings.
By the way, have a look at
the X32 console as it is going to be a world beater (Midas pre amps, etc and Klark Technik DSP and you can't get much better than either of these companies and a $20mil production facility in GERMANY to manufacture it !!!!!)---- I do not not work for Behringer and have no association with them apart from being a very happy user of their products for many years.
